Description

Display name of broadcasting station of received broadcasting signal

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control method of a television system. In particular, when a broadcast signal transmitted from a broadcast station other than a designated broadcast station is received through a tuned broadcast channel, an OSD (On Screen Display) signal is generated to transmit the received broadcast signal. The present invention relates to a method for displaying a broadcast station name of a received broadcast signal informing a user of a broadcast station name.

In general, television broadcasts, such as news, music, entertainment, culture, sports, broadcast signals produced by broadcasting stations through a transmission antenna, the receiver installed in the home receives it and provides it to the viewers. Therefore, in order to receive a broadcast signal of a specific broadcaster from among broadcast signals transmitted from a plurality of broadcast stations through a receiver, first, channel selection and tuning operations of the television system must be performed. Tuning designation is to tune the reception frequency of the tuner and detect a broadcast signal, and when a broadcast signal is detected, for example, the Seoul Broadcasting System (SBS) is designated as a channel 6. Such selection is usually made during the manufacture of the product. On the other hand, tuning in a designated television system generally rotates the channel knob or presses a remote control key. By this operation, the tuner's reception frequency is changed to receive a broadcast signal of a specified channel. However, in some cases, a broadcast signal transmitted from a broadcast station other than the designated broadcast station is received through the tuned broadcast channel. In other words, in the era of localization, a large number of local civilians have been launched for local broadcasting in Korea, but a small number of local civilians cannot produce all their programs. A nationwide broadcasting network was used to exchange each other.

Therefore, at a specific time, other local people receive and amplify the broadcast signal produced and transmitted by the local people's community, A, and provide the viewers with their own programs. Use the way. Therefore, there is a case where a broadcast signal transmitted from a broadcasting station other than the designated broadcasting station is received through the tuned broadcasting channel. However, the viewer may be aware that the received broadcasting signal is a self-produced program produced by a local community in his area or a local community in another area. It may be confusing because you don't know if the program is produced by.

Accordingly, the present invention has been invented to solve the above problems, and the broadcasting station name data is detected from a broadcasting processing system (KBPS) signal including various information related to broadcasting, and the detected broadcasting station name data is tuned. It is an object of the present invention to provide a method of displaying a broadcast station name of a received broadcast signal in which an OSD (On Screen Display) signal is generated to inform a user of a broadcast station name that transmits a received broadcast signal.

In order to achieve the above object, the present invention provides a control method of a television system, comprising: a first step of receiving a broadcast signal of a channel tuned through a tuner, and included in the broadcast signal received in the first step; A second step of detecting broadcasting station name data from the broadcasting processing system (KBPS) signal and comparing the broadcasting station name data with the designated broadcasting station name of the tuned channel previously stored in the memory; and in the second step, the broadcasting station name and the tuned channel And if the designated broadcasting station name is not the same, a third step of outputting an OSD (On Screen Display) signal and displaying the broadcasting station name of the received broadcasting signal through the receiving hall.

1 is a block diagram schematically showing the configuration of a television system to which the present invention is applied, and selectively receives and amplifies a broadcast signal desired by a viewer among broadcast signals output from a plurality of broadcasting stations, and provides stable amplification and required selectivity characteristics. A tuner 12 which converts an intermediate frequency signal, i.e., 58.75 MHz in the case of a video signal and 54.25 MHz in the case of an audio signal, is connected to the reception antenna 11. The voice intermediate frequency signal among the intermediate frequency signals converted by the tuner 12 is applied to the voice signal processor 13. The voice signal processor 13 extracts and amplifies the 4.5MHz voice medium frequency signal from the input 54.25MHz voice medium frequency signal, and FM-detects the amplified 4.5MHz voice medium frequency signal to extract the voice signal. The extracted voice signal is amplified by the voice signal amplifier 14 and provided to the speaker 15. Meanwhile, among the intermediate frequency signals converted by the tuner 12, the image intermediate frequency signal is applied to the image signal processor 16. The image signal processor 16 amplifies and detects the input image intermediate frequency signal to detect the image intermediate frequency. Extract the video signal from the signal. The extracted video signal is amplified by the video signal amplifier 17 and provided to the water pipe 18. In addition, a microcomputer (not shown) for controlling each component of the television system is provided by a data detector 19 which reads a broadcast processing system (KBPS) signal included in the broadcast signal received by the tuner 12 and extracts broadcast station name data. 21). The microcomputer 21 receives the broadcast signal of the tuned channel by controlling the tuner 12 according to the switching state of the power switch 20, and also transmits to the broadcast station name and the memory 24 detected by the data detector 19. It compares the preset broadcast station names of the pre-stored tuned channel, and controls the OSD generator 22 accordingly to display the broadcast station name of the received broadcast signal through the receiving pipe 18 to inform the user.

2 is a flowchart illustrating a method of displaying a broadcast station name of a received broadcast signal according to the present invention applied to a television system configured as described above.

When the power switch 20 is turned on to drive the television system (101), the microcomputer 21 receives the broadcast signal of the channel tuned through the tuner 12 (102). Accordingly, the data detector 19 reads the broadcast processing system (KBPS) signal included in the broadcast signal received from the tuner 12, detects the broadcast station name data, and applies it to the microcomputer 21 (103 to 104). ). When the broadcasting station name data of the received broadcasting signal is applied to the microcomputer 21, the microcomputer 21 determines whether the detected broadcasting station name is the same as the designated broadcasting station name of the tuned channel previously stored in the memory unit 23 ( 105, if the broadcasting station name and the designated broadcasting station name are not the same, the OSD generating unit 22 controls the OSD signal to inform the viewer of the broadcasting station name to the video signal amplifying unit 17 (106). The above operation is repeated 107 until the power switch 20 is turned off and the television system stops driving.

As described above, the present invention detects broadcasting station name data from a broadcasting processing system (KBPS) signal including various information related to broadcasting, and if the detected broadcasting station name is different from the designated broadcasting station name of the tuned channel, OSD (On Screen) is displayed. Display) by generating a signal to inform the user of the name of the broadcasting station that has transmitted the broadcast signal, it is possible to prevent the confusion of the viewer due to the change of the broadcasting station.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
